Root Level Commands

:AER?

(Arm Event Register)
Query
:AER?
The :AER? query reads the Arm Event Register and returns 1 or 0. After
the Arm Event Register is read, the register is cleared. The returned value
1 indicates a trigger armed event has occurred and 0 indicates a trigger
armed has not occurred.
Arm Event Returns
N O T E
:AER? will allow the Arm Event to return either immediately (if you have armed but not
triggered) or on the next arm (if you have already triggered). However, *CLS is always
required to get an SRQ again.
Once the AER bit is set, it is cleared only by doing :AER? or by sending a
*CLS command.
